To tackle the growing demand for grid-scale energy storage, the ALPHEUS project proposes a novel low-head pumped hydro storage system aimed for coastal application in countries where the topography does not allow for traditional high-head storage. This system consists of a reversible pump-turbine technology with two contra-rotating runners coupled...

... variable speed power take-off is chosen due to its improved flexibility and efficiencies across a wider range of operating conditions (Vasudevan et al. 2021). The proposed system uses direct-drive transmissions : Modelling Domain for CFD comparison, including hub, struts and runners. ...
